Patent CA-2193349-C (CA)

Abstract: La limite apparente d'élasticité d'un profilé obtenu par laminage à froid est accrue et rendue effective en exerçant une contrainte d'une valeur déterminée lors du formage à froid d'un processus de laminage en ligne, puis en procédant à un vieillissement par écrouissage d'une certaine force. Ce vieillissement par écrouissage consiste à élever la température du profilé d'acier à un point se situant en dessous de 500 ~C puis à la maintenir à une température élevée pendant moins de 30 secondes. La chauffe est réalisée en l'occurrence au moyen de réchauffeurs à induction (16), et l'écrouissage peut être réalisé par passage dans un bain de galvanisation (17) en ligne puis refroidissement de l'acier dans un bain de trempe (18). L'effet en sera renforcé par un travail à froid ultérieur et par la contrainte supplémentaire que produira le laminage qui s'ensuivra (19). Pour une teinte d'acier déterminée, ce sont les paramètres de température et de durée ainsi que le coefficient initial de laminage dans le laminoir (10) qui permettent de déterminer le niveau d'accroissement de la limite apparente d'élasticité.

Abstract: A GMAW gun has a nozzle that is axially slidable over a gas diffuser. The nozzle is positively located in one of two different positions by a double counterbored insulator in cooperation with an insulative retaining ring. When the double counterbored insulator is installed in a first orientation on the gun, the nozzle abuts a first surface of the double counterbored insulator to provide a first positive stop. When the double counterbored insulator is installed in a second orientation, the nozzle abuts a second surface of the double counterbored insulator to provide a second positive stop. The various components of the gun are dimensioned such that a contact tip protrudes from the nozzle when the nozzle is at the first positive stop and the contact tip is recessed into the nozzle when the nozzle is at the second positive stop.

Abstract: The present invention is generally directed to a system and to a process for dispensing a volatile liquid fertilizer and particularly ammonia  into  a  field.   The ammonia is placed in a vessel under sufficient pressure to maintain a substantial portion of the ammonia in a liquid form.  From the pressurized vessel, the ammonia is fed to a distribution manifold where it is ultimately injected into a soil through a plurality of dispensing tubes.  According to the present invention,  a constant pressure flow rate control  device  is  placed  at  each  dispensing  tube  for metering  the  amount  of  ammonia  fed  to  the  soil.    In particular,  the flow control devices allow ammonia to be dispensed from the system while maintaining sufficient back pressure within the distribution manifold to maintain the ammonia in a liquid form.   By preventing vaporization of the  ammonia  within  the  system,  uniform  and  accurately controlled flow rates can be dispensed from the dispensing tubes.

Title: Use of the green fluorescent protein as a screenable marker for plant transformation
Inventor: MILLER MIKE
IPC: C12N15/82
Filed: 1997-05-01
Granted: 2005-10-25
Abstract: A method for the production of transgenic plants is provided in which a vector carrying a gene encoding the green fluorescent protein is introduced into cells, the cells are screened for the protein and transformed cells are selected and regenerated. The cellular toxicity of the green fluorescent protein is circumvented by regulating expression of the gene encoding the protein or directing the protein to a subcellular compartment where it is not toxic to the cell. DNA constructs are provided for cell transformation in which the expression of a gene encoding the green fluorescent protein is placed under the control of an inducible promoter. In addition, DNA constructs are provided in which a nucleotide sequence encoding the green fluorescent protein is operably linked to a signal sequence which directs the expressed protein to a subcellular compartment where the protein is not toxic to the cell. Oxidative stress to plant cells transformed with GFP also can be ameliorated by transforming cells with an expression vector comprising genes encoding GFP and an oxygen scavenger enzyme such as superoxide dismutase. The toxicity of GFP in transformed plants can be eliminated by excising the screenable marker gene following detection of transformed cells or sectors. The FLP/FRT system is used in conjunction with GFP as a visible marker for transformation and FRT excision. A nucleotide sequence optimized for expression of the green fluorescent protein in plants is also provided.

Title: Redundant call processing
Inventor: LEE WONSEOK
IPC: H04Q3/00
Filed: 1999-05-31
Granted: 2003-05-13
Abstract: A telecommunications network includes at least an active and a standby call server, the standby call server becoming active upon failure of the active call server. To facilitate rapid switch-over from the active to the standby call server and to prevent the loss of call processing data for calls in the call setup stage, the active call server sends call information to the standby call server during intervals in which the active call server is awaiting subsequent signaling messages from elements of the telecommunications network. In this way, the standby call server has the call information needed to commence call processing upon failure of the active call server, and the active call server makes efficient use of time while awaiting a reply signaling message.
